Spinal thoracic forming system

Abstract

The present invention relates to a spinal thoracic forming system, the spinal thoracic forming system comprises a connecting structure and a fixed structure; the top of the connecting structure gradually becomes a cylindrical shape, and can be connected to a posterior spinal rod fixing system through a transverse connector, the connecting structure is made of a highly elastic non-magnetic stainless steel material, and can be slightly moved with the undulation of a thorax during breathing; the arranged claw structures are arranged on both sides of the fixed structure, the fixed structure is provided with screw holes at the central positions of the claw structures on the opposite two sides, can be fixed to a broken end of a rib by screws. The spinal thoracic forming system has the advantagesthat after the spinal tumor and the ribs are removed, an effective fixed connection relationship is formed between the removed ribs and the spine, the reconstruction of the spine and the thorax afterspinal tumor and rib are removed can be realized, which overcome the serious respiratory complications caused by thoracic collapse after resection of the diseases, the quality of life of patients isimproved, and the mortality caused by respiratory failure is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a spine thoracoplastic system. Background technique [0002] At present, there is no effective method for multi-level reconstruction of chest wall and ribs after multi-segment en bloc discectomy for thoracic vertebral tumors, and there are high technical requirements. Currently, there are few reports on surgical techniques for effective and safe reconstruction. In order to resolve extensive chest wall defects and prevent severe respiratory dysfunction, some surgeons previously proposed a reconstruction method through a posterolateral approach. The main steps of this method are to fix the titanium rods on the surface of the spine with pedicle screws in order to ensure the effective reconstruction of the spine, thorax and ribs after resecting the spinal segment and the corresponding ribs involved by the tumor, so that the upper and lower spine can be Continuation of f...

Problems solved by technology

However, after a spinal tumor and ribs are resected in one piece, a highly elastic non-magnet structure is used to form an effective and integral fixed connection relationship with a fretting effect between the resected ribs and the spine, and to achieve sp...
